+3. La fonction ne fait pas son travail car elle ne modifie la variable a que dans le bloc
+de la fonction. Il faut donc la renvoyer et assigner à la variable x la valeur renvoyée
+par la fonction zero() :

+# include <stdio.h>
+# include <stdlib.h>
+
+
+double zero(double a) {
+  a = 0.0;
+  return a;
